MICHAEL HENNASY, OF CRAWFORD, NEW JERSEY, ASSIGNOR TO HIMSEL-F AND JOHN ADAMS, OF SAME PLACE.

IMPROVEMENT IN CLAW-BARS.

Speciication forming part of Letters Patent No. 80,072, dated July 21, 1868.

To all whom it 'may concern:

Be it knowuethat I, MICHAEL HENNAsY, of Crawford, in the county of Union and State of New Jersey, have invented a new and Improved Claw-Bar; and I do hereby declare that the following is a full and exact description of the same, reference being had tothe accompanying drawings, and to the letters of reference marked thereon.

My invention consists in attaching to an ordinary claw-bar, A, a short claw-bar, B, by the lips C C, swinging on the pin d. On the opposite side I attach aproject-ion for a fulcrum, E.

In commencing to use the bar in raising spikes along a railroad or elsewhere, the bar B is swung back under the bar A, and is out of the way. Then the bar A is used in the ordinary manner, and raises the spike a short distance. At this point, without my improvement, an extra hand (and sometimes two) is required, with an additional fulcrum placed under the bar for the purpose o't1 raising the spike out as far as is needed. To dispense with this extra help and extra fulcrum this bar has been invented, t'or when with the common bar the spike is raised as high as it may be the-whole bar is turned-over and the bar B is swung down above the end ot' the bar A, as indicated by the dottedlines F in Fig. 1, and the fulcrum E is then .in its position below the bar B and the spike is raised by one man as high as is necessary, thereby saving a large amount of expense in not requiring the extra help.

I therefore claim as myinvention and desire to secure "by Letters Patent- The claw-bar Band fulcruin E, in combinal tion with the claw-bar A, substantially as and for the purpose specified.

MICH AEL HENNASY.
